Really feel terrible.
IIRC it took Beckham about a year (I was impressed Becks came back as he was older and had did almost everything but still wanted to come back). I think it is very slow healing due to low blood flow in the area
Long might have a chance to grow out a impressive mullet in that time!!
Best of luck to ALo as impressive player on top of impressive person/path -
Lawrence Taylor also had this injury in his mid-30s.. He came back within less than 12 months to play one final season after the injury.
